Subject: bug#73559: [PATCH] fix NS build focus-in event processing
Date: Sun, 29 Sep 2024 22:47:46 -0400

In Emacs NS build, frames don't respond to focus-in events right away.
Instead, they store the focus-in event and process it (and other queued
events) whenever some other event happens to occur on that frame.

This patch kicks the NS event loop immediately when a focus-in event
happens, allowing Emacs to respond to focus-in events without some other
event triggering the processing.
